BED CONSTRUCTION. 1

PatentedFeb. 8,1916.

Application filed August 14,1912. Serial No. 714,978.

To all whom it may concern:

Be it known that I, WVILLIAM J. GRoTEN- HUIS, a citizen of the UnitedStatesresiding at Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Bed Constructions,

of which the following is a specification.

This invention relates to the art of bed structures, having referencemore particularly to that type of bed structures wvherein arectangulanbed-spring frame is I structure of the rigid-corner type.

The principal objects which my present invention has in view are, first,to provide a simple and convenient means for-not only supporting thecorners of the bed-spring frame upon the side-rails of the bed-steadframe, but also positively securing said corners to said side-rails, inorder to prevent teetering of the bed-spring frame on its supports andinsure a level and flat condition of the mattress-supporting surface ofthe bed-spring; second, to provide a simple and adjustable means forthus supporting a bed-spring upon, and securing it to bedstead frames ofslightly different widths; and, third, to provide a simple and efficientconstruction for preventing accidental shifting, either laterally orlengthwise, of the bed-spring frame upon and relatively to the bed-steadframe.

In the accompanying drawings I have illustrated a simple and approvedembodiment of my invention as applied to bed constructions of both thecushion-corner and rigid-corner types; and referring thereto- Figure 1is a perspective elevation of cooperating corner-portions of thebed-stead and bed-spring frames, illustrating the application of myinvention to a bed of the spring or cushion-corner type, as illustratedin my patent above referred to. Fig; 2 is an enlarged cross-sectionaldetail, taken on the line 22 of Fig. 1. Fig. 3 is a view similar to Fig.1, illustrating the application of my invention to a bed of the rigid- 7corner type. Fig. 4 is a viewsimilar to Fig. 2 takenon the line l-1 ofFig. 3.

Referring first to Figs. 1 and 2, 5 desig- I nates a corner post of thebed-stead frame,

and 6 is a side-rail thereof, this latter being of the angle-iron formextensively employed to form the side-rails of metalbeds.

7 designates an'end bar, 8 a tubular side bar, and 9 a connecting cornerbracket or the bed-spring frame, a fragment of the mattress-supportingsurface thereof being shown at 10. v

The bedspring frame here shown is elastically supported at its cornersupon cushioning springs 11 that are housed within loop-shaped portionsof the corner brackets. The lower endof the spring 11 rests in acup-shaped seat 12 formed on a transverse supporting member that extendsbetween and is stepped upon the side-rails 6 of the bed-stead frame.This transverse supporting member, as herein shown, consists of a pairof metal end castings each comprising an outer, .substantially flatportion 13 that is stepped directly upon the side-rails 6, theintermediate cup-shaped portion 12 forming the spring seat, and an innershank portion 1 1; and an intermediate bar 15 rigidly'connected to andextending between the shank portions 14 of the end castings. Thisendcasting is loosely"connectedto the corner bracket 9 in a manner toafford freedom of action to the spring 11 stepped on the upper surfaceof the --side'-" rails 6 of the bed-stead frame, is provided with a.longitudinal slot 17. Beneath the lug 13 is an attaching devicecomprising a clamp member 18 and a fastening bolt 19.

The clamp member is formed with an outer free end portion 20 thatengages the under side of the side-rail, an intermediateverticalshoulder portion 21 that abuts against the inner edge of the side-rail,and an inner shank portion 22 that is formed with a bolthole toreceive'the stem-of the bolt 19.-

' .In the rigid-corner construction shown in Figs." 3 and 4c, the cornerbracket 23 is cast with an integral laterally projecting supporting lug2 1 formed with a longitudinal slot 17; and cooperating therewith is aclamp member 18 having an outer free end portion 20, an intermediatevertical shoulder portion 21, and an inner shank portion 22 apertured toreceive a bolt 19; this attaching mechanism being a duplicate of thatshown and described in connection with Figs. 1 and 2.

The foregoin description, taken with the illustration, will make readilyapparent both the simplicity of my invention and its capacity forsecuring the stated objects of the invention. It will be seen that by itthe four corners of the bed-spring frame are clamped to the side-railsof the bed-stead frame so that the former is held level, and teeteringor Warping is impossible. The clamping action, and the abutment of theshoulders 21 or 21 against the inner edges of the siderails of thebed-stead frame, effectually prevent either lateral or longitudinalshifting of the bed-spring frame upon the bed-stead frame; and the slots17 or 17 permit adjustability of the supporting lugs and clamps to a fitupon bedstead frames which may vary in width to an extent not exceedingthe adjusting capacity of the slots.

In either form of my invention the nut 25 on the fastening bolt engagesthe shoulder 26, whereby a sort of lock-nut is formed to preventloosening of the clamp. The element 18 is composed of the upper andlower portions which overlap, the outer edge of the upper portionforming the shoulder 21, and the inner edge of the lower portion formingthe shoulder 26, whereby both said element and said nut are held againstturning about said bolt. As shown, said bolt 19 or 19 is formed at itsupper-end with a screw head or other suitablemeans for rotating the boltin the nut 25 when it is desired to fasten or unfasten the device.

I do not limit myself to the exact construction shown and described.

I claim- 1. In combination, a pair of bedstead side rails, a bed bottomhaving corner members and side bars disposed between said rails, anddevices for securing the bed bottom in place on said rails, each devicecomprising a bed bottom supporting projection extendmg upon the adjacentrail, an element for engaging both the under side and the inner edge ofsaid rail, and means for removably securing said element to the underside of said projection, said device having provislons for theadjustment of said element to- Ward and away from the adjacent side ofthe bed bottom, including a slot in said projection, and said meansincluding a bolt in said slot, said bolt having a nut on the lower endthereof, said element having a shoulder for preventing rotation of saidnut, and said bolt having its upper end provided with means for therotation thereof to tighten or loosen said element.

2. In combination, a pair of bedstead side rails, a bed bottom havingcorner members and side bars disposed between said rails, and devicesfor securing the bed bottom in place on said rails, each devicecomprising a bed bottom supporting projection extending upon theadjacent rail, an element for engaging both the under side and the inneredge of said rail, and means for removably securing said element to theunder side of said projection, said device, having provisions for theadjustment of said element and means toward and away from the adj acentside of the bed bottom, said element having upper and lower shoulderswhich face in opposite directions to respectively engage said rail andmeans, one said shoulder thereby holding said means to permit operationthereof.

3. In combination, a pair of bedstead side rails, a bed bottom havingcorner members and side bars disposed between said rails, and devicesfor securing the bed bottom in place on said rails, each devicecomprising a bed bottom supporting projection extending upon theadjacent rail, an element for engaging both the under side and the inneredge of said rail, and means for removably securing said element to theunder side of said projection, said device having provisions for theadjustment of said element toward and away from the adjacent side of thebed bottom, said means including a nut, and said element having meansfor holding said nut against rotation.

4:- In combination, a pair of bedstead side rails, a bed bottom havingcorner members and side bars disposed between said rails, and devicesfor securing the bed bottom in place on said rails, each devicecomprising a bed bottom supporting projection extending' upon theadjacent rail, an element for engaging both the under side and the inneredge of said rail, and means for removably securing said element to theunder side of said projection, said device having provisions for theadjustment of said element toward and away from the adjacent sine of thebed bottom, said element having upper and lower portions which overlap,the outer edge of the upper portion engaging the edge of said rail, andsaid means including a bolt provided with a nut which engages the inneredge of said lower portion, thereby preventing both said element and nutfrom turning about said bolt.
